I realize that excessive consumption of vitamin A (generally considered to be greater than 3000 micrograms per day) can have adverse effects on one's health. I generally eat one to two 10 oz (measured raw) sweet potatoes per day, which I believe puts me over the recommended limit for vitamin A intake. However, I was under the imrpession that the vitamin A found in sweet potatoes was in the form of beta carotene, a provitamin which is then converted by the body into vitamin A. If I remember correctly, if one already has ingested the necessary amounts of the vitamin, then beta carotene will not be transformed; thus, there is no resulting excess of vitamin A
Should I be worried w/ my consumption of sweet potatoes?
